Brief Description: [See More | Edit]

Among the species with thick‐walled cystidia P. rubronigra can be recognized by its fragrant odor, some pleurocystidia with walls up to 1.5 μ thick, very dark reddish brown color over the disc of the pileus as dried, and lack of brown squamules over the lower part of the stipe. In the dried state the whole basidiocarp of P. decorata is much paler in color and when fresh its stipe has brown squamules of veil remnants, and it typically lacks a fragrant odor. Both show variation from thin to thick‐ walled pleurocystidia.
P. vinaceobrunnea lacks a fragrant odor, has pleurocystidia with walls 2‐3 μ thick, and no caulocystidia were found in an examination of dried material. Also its cystidia measure 60‐115 μ long. P. humii with pleurocystidia having walls to 3 μ thick, has a fragrant odor, and a veil so poorly developed as to scarcely leave a zone of fibrils where it breaks. Also it appears to be a more slender species. This stirps, with the exception of P. velaglutinosa appears to be a “collective” species, and as indicated in other similar situations, comparative studies in culture are badly needed.
